Be itknown that 1, (inches H. Bowman, a citizen of the United States,and a resident of the city of New Yorlt, borough of Manbutton, in thecount and State of New York, have invente a new and useful HitchforTractors, of which the following is a full, cheer, and exactdescription.

This invention relates to a hitch for tractors, and has for an object toprovide an improved construction which may be connected to a tractor ofsubstantially any kind and which will prol'nnly hold one ormoreimplemen'ts in position to be moved by the tractor.

Another Obfi'GC of the invention is to pro ville ii'hitch or tractorswhich is especially desirable for connectin plows to the tractor, theconstruction icing such that a ready adgustment may be secured forcausing the p ow to assume various depths while it proper strain isbrought to bear thereon continuously.

A' further object of the invention is to provide a hitch in which thereis enndjusb able swinging member and bracing members oo-ucting therewithwhereby the implement connected with the hitch may have its line ofdraftshifted to difi'erent horizontal levels without varying theconnection with the tractor.

.An additional object is to provide a hitch, which includes in itsconstruction. means for limiting the side movement of an implementconnected to the hitch and also limiting the upward movement.

Fig. 6 is a view similar to Fig. 5, but showing the front part of thehitch tilted to a'considemble angle, while the rear part is still in ahorizontal position.

Fig. 7 is n fra mentar' sectional view throu h Fig. 4 on ine 7- Re errinto the accompanying drawings by numeral s 1 indicates a tractor of anydc siied kind, as for instance a tractor of the type shown in my PatentNo. l,3%,694, issued December 9, 1919. In connecting the, hitch with thetractor 1 any suitable connecting means may be provided which will ullowthe tractor to move or oscillate freely transversely of its direction oftravel, and will permit the plow and associate parts also to rock freelylaterally. This connection may be in the form of an attachment 2, boltedor otherwise rigidly secured to the casing of the tractor, and a yoke 3provided with fittings; 5. These fittings have one or more squareopenings for receiving the square shaft 7, though if desired a roundshaft could he used and a key or other means Erovided for preventingrotation. It will e observed that the fittings 5 are in the.

nature of clevises and are pivoted on the yoke 3 so as to swing in ahorizontal plane, while said yoke .is provided with a. sleeve 4 adaptedto swing in a vertical plane on a. pin 4' carried by the attachment 2.If desired a pair of handles 6 could be pivotally mounted on theattachment 2 and resiliently supported by a suitable spring 6 in orderto pizovide steering means at a convenient Point.

It wil be noted that the handles'ti are not carried by the hitch, norare they connected to the implements pulled by the hitch, but

are connected to henttachment 2 carrying the joke 3-,

Rigidly inounted onthe square shaft 7 is a rack -'8 havinghuba 9. and10' which are.

zontal section 19, which in turn merges into a vertical section paralleland adjacent the section 17, said section 2 being bent oror forpresenting a guide and an abutment 2t. Bolts or rivets 22 extend throughthe, sew tions 17 and 2t) and also through the lever 21% for holding thesame in proper plat-e. and for rigidly securing the same to the platesl3 and l4. The stop 21 is pi'e'l'orably provided with a round opening 24for receiving the upper part ol the latc-h pin 25, which is pointed atthe upper end while the horizontal section it) is provided with an elongated opening 26 for rereiring the head 27 of latch pin 25, which isshaped to easily slide therethrough. The opening 21 has a diameter equalto the narrowest point of the opening 20 so that the hitch pin 2 mayfreely pass upwardly through the opt-nine or slot 530 and the upper partthrough the opening 24. A spring surrounds the latch pin 33 and rests atone end against the head 2i and at the opposite end against the stop 1!?whereby the head 27 is urged dowlr \\nl' ll l' and into engagenn-nt withthe teeth ol the rack H This oons'truotion and arrangement 1)X\J.l lP,nfor lot-kiln, the side plates I55 and l4 in any desired positionnotwithstanding! the fact they are. loosely mounted on the hubs 9 and toof the ruck 8. The lever 23 at the upper end is provided with a suitablegrip ext nsion 29 (Fig. which pirotally mounted on the lever 23 andwhich has a rod or wire 3" pirotally connected therewith and also withthe upper end of the pin so that whenever desired the operator may moremember 29 against the lever .13 and thereby disengage the rutrh 25 fromthe rack 8 so as to swing the plates i i and H upwardly or downwardly asde sired. The rrar part of the plutes 13 and t are bent at 31 and 32respectively (Fig l) and then formed into end sections 33 and 34, whichhare riveted or otherwise,

rig-idly secured thereto auxiliary'seetions 33' and 34" which produce anextra thickness so that the rounded ends of the pin 35 may have amplejournals. It; will be noted that the members 33 and 34 and theirauxiliary sections are provided with apertures for accommodatingthe pin35 which pin is preferablys uare in cross section. except at the ends,an tits flat'wise against the adjustable disk-like plate 3th Bolts"???and 38 pass through suitable apertures in pin 35 as shown in Fig. 4 andalso-through slots 3'.) and {il in the disk 36 so aslto clamp these twomembers together The disk 36 isv provided with top and hottoni ears 41and 42 through which a. vertical pin 43 extends, said pin being! held inposition in any desired manner as for instance hv a set screw 44, thoughif desir'od it could be provided with a head. or a hon-d and nut. Thepin 43 not only extaids through the ears 41 and 42, but also said onwill err-tin through the ears or barrels 45 and lll ol' the dral'tilulus l7 and 48. 'lhesc dral't plates are bolted or otherwise rigidlysecured to the beam Not the ilow f l or other llilpltlln'llt heingmoved. 'lhe hinge rollstl'lu'lion pro rided by the ears or barrels l5and 4t; and the pin 43 permits a free horizontal swinging movement onthe pin 4-3. In order to limit this l'rri' lnoi'enitut springs '71 are(-ounortod with the ear 4! ol the plate 47 while similar springs 52 areconnected with plate 4 'llleno springs are also connected with the diskFlt whereby any appreciable side morement in a horizontal plane will beresisted and the parts will he brought back unto matirally to a neutralrentrul iosition. ln ruse the ground is sulistantiu ly level the partswill be adjusted as shown in Fig. 5. but in ruse one wheel ol thetractor is in a l'urrou the bolts 37 and 3B are loosened and the partsadjusted to the position shown in Fig. (i, al'ter whirh the nuts arelightened until there is a rigid (UlHlU-ll ion between the disl: 36 andthe pin 35. This will allow the lluw tor to trure] with one wheel lowerthan the other and if desired at an angle. while perinilting' the plowfil to travel in a horizontal position. In tart iin adjustment of thiskind is essential when n plow similar to plow is used, as anyappreciable tiltin; thereof would cause the plow to more outot theground automatically.

When the parts vtire all connected up as shown in Figs. 1, 2 and 4 forinstance, and it is desired to cause the plow 50 to plow as deep :1furrow as possible lever 23 is moved over to its extreme lower positionas shown in dotted lines in Fig. 1. This will rause the plates 17-; andH. pin "15 ulnl tlSStl riate parts to more downwardly to the dottedposition shown in Fig. 1. so that when the tractor is started the plowwill automath cally ,move downwardly to the proper level and thusproduce the furrow desired, as the line of strain isiat a; lowerpointthan when the partsit ositionslrown in full lines in p fiction'pmdu'ees a twistingstrliin onthe slitift or bar 7, but as th eipowcrused ia'boinpuratively light strain. In case ow is used, or if for anydesired retlison it should be thought necessary to ii'ssistbar Tintaking up the strain the link 53 would he used. said link beingpivotally connected at 54 to the engine casing and provided with anumber of notches 55 at its free end, A suitable pin 56 is connectedwith late 33 positioned to interlock with one o the notches 55 when thelink 53 is used so that-part of the strain will be communicsiedto thecasing of the engine at pivotal point 54. The operator may at;substantially any time raise'the' link- 53 and hold the same in anelevated position so as to eithrjtransfer all of the strum to impke careof this Ill llt)
